Course Overview
This session of the seminar is focused on the standards EN50126, EN51028, EN50129 and EN50159 and intended to provide an overview of the requirements for a safety demonstration. For this purpose, the entire life cycle of a railway system, starting with the system definition and identification of the hazards, determining the safety requirements and evidences of control of hazards is described.
Part 1: EN50126 (RAMS) - 1st Day
- Overview: European directives, understanding standardization, standards in the railway signalling technology
- Elements of RAMS and affecting factors
- Risk / Risk Analysis
- Safety Integrity
- Life Cycle Model
Part 2: EN50129 (System Safety) – 1st Day & 2nd Day
-
Process of risk and hazard control ("Hour-Glass Model")
- System definition, hazard identification, consequence analysis, risk assessment,
- THR assignment, root cause analysis, common cause analysis, SIL assignment
- Safety integrity levels
- Quality Management
- Safety Management
- Safety demonstration
- Identification of safety requirements
- Technical and functional safety
- Basic methods (FMEA, FTA, Markov models)
Part 3: EN50159 (Communication) – 2nd Day
- Safety transmission system reference architecture
- Overview of the threats
- Overview of the necessary steps to control
- Calculation of the hazard rate of the transmission channel
Part 4: EN50128 (Software) – 3rd Day
- Definitions
- Software safety requirement levels (SSAS)
- Personnel and responsibilities
- Life Cycle Model
- Use of COTS software
- Requirements of the phases (sections)

Part 5: Common Safety Method on Risk Evaluation and Assessment – 4th Day
The European Commission Common Safety Methods (CSM) on Risk Evaluation and assessment regulation 352/2009 now provides a legal obligation and mandatory framework for the evaluation and assessment of risk associated with engineering, operational and organizational changes to the railway in EU countries. The part of the CSM-seminar course provides an understanding of the CSM regulation and risk assessment framework, as well as guidance on implementation.
- Résumé of Risk-analysis principles
- Introduction to the CSM regulation
- System definition
- Hazard identification
- Risk acceptance principle and Risk Evaluation
- Hazard management
- Demonstration of compliance with safety requirements
- The Assessment Body
Options on 5th day: Functional Safety Certification Program (Examination 3 hours)
The European Commission Common Safety Methods (CSM) on Risk Evaluation and assessment regulation 352/2009 now provides a legal obligation and mandatory framework for the evaluation and assessment of risk associated with engineering, operational and organizational changes to the railway in EU countries. The part of the CSM-seminar course provides an understanding of the CSM regulation and risk assessment framework, as well as guidance on implementation.
- Level 1 examination (without precondition)
- Level 2 examination (precondition is fulfilling of following requirements)
- 6 years of industry experience in Functional Safety technology
